As for users of the Samsung Epic 4G, we have bad news. Three days ago, as we reported, users of the device received an OTA upgrade for Android 2.2 with the option to install the software manually. However, some problems have developed and some of those who installed the update have had problems with the handset's data connectivity or loading data from a microSD card. So for now, Samsung and Sprint have pulled the update as they work on fixing the problem. If you have experienced some difficulties in getting your Samsung Epic 4G to work, a hard reset is recommended. Back up your data and click on this link to the Sprint community help thread to see how it's done.
The last bit of Android 2.2 news we have today deals with the HTC Aria. Users of this phone will find out from AT&T's Facebook page how to upgrade the device, starting on Friday. Because the Aria does not have the hardware to run every feature available in the the Froyo update, certain things that you might see on other Android 2.2 devices will not run on the handset. The phone will get the JIT compiler that should provide a bump up in speed when it comes to running the browser and some apps.
So that is the Android 2.2 news for the day; hopefully it will all be good news in the not too distant future.
